Association between Variation of Troponin and Prognosis of Acute Myocardial Infarction before and after Primary Percutaneous Coronary Intervention

Figure 4

Cumulative incidence of myocardial infarction or cardiac death in patients with troponin concentrations. Patients were stratified into four groups based on the △cTnI level. Q1: first quartile (green line); Q2: second quartile (blue line); Q3: third quartile (grey line); and Q4: fourth quartile (black line). (a) Kaplan–Meier curves depicting the cumulative probability for MACE (log rank  = 0.035). (b) Kaplan–Meier curves depicting the cumulative probability for mortality (log rank  = 0.049). (c) Kaplan–Meier curves depicting the cumulative probability for recurrent myocardial infarction (log rank  = 0.150). (d) Kaplan–Meier curves depicting the cumulative probability for angina pectoris (log rank  = 0.026). MACE: major adverse cardiovascular events.
